TEAS 7 science practice questions Questions
Question 1 of 5
Which property of matter measures the amount of space occupied by an object?
Correct Answer: D
Rationale: Volume is the property of matter that measures the amount of space occupied by an object. Mass refers to the amount of matter in an object, weight is the force of gravity acting on an object, and density is the mass of an object per unit volume. Volume specifically quantifies the space occupied by an object, making it the correct answer in this context.
Question 2 of 5
What type of energy does a stretched rubber band possess?
Correct Answer: B
Rationale: When a rubber band is stretched, it stores potential energy due to its position or configuration. This potential energy can be converted into kinetic energy when the rubber band is released and returns to its original shape. Therefore, the correct answer is potential energy, as the energy is stored in the stretched rubber band and can be released upon returning to its original state. Choices A, C, and D are incorrect because kinetic energy is associated with motion, thermal energy is related to heat, and mechanical energy is a broader category that includes both potential and kinetic energy.
Question 3 of 5
What is the term for a repetitive, involuntary muscle contraction that can cause pain and stiffness?
Correct Answer: B
Rationale: A spasm is a repetitive, involuntary muscle contraction that can cause pain and stiffness. While cramps are a type of spasm, not all spasms are cramps. Tics are sudden, repetitive movements or sounds made involuntarily. Fibrosis refers to the formation of excess fibrous connective tissue in an organ or tissue as part of a reparative or reactive process. In this context, a spasm best fits the description provided, making it the correct answer. Cramp, although related to spasms, is more specific and not the general term being sought. Tic does not describe a muscle contraction but rather sudden movements or sounds. Fibrosis does not directly relate to muscle contractions but rather to the formation of excess fibrous tissue in organs or tissues.
Question 4 of 5
Which statement accurately describes the electron cloud model of the atom?
Correct Answer: B
Rationale: The electron cloud model of the atom describes electrons as occupying specific energy levels around the nucleus with varying probabilities. This model does not suggest that electrons precisely orbit in defined paths as stated in option A. It acknowledges the wave-like behavior of electrons and their uncertainty in position, which is not accounted for in options C and D. Option C is incorrect as electrons are not clustered tightly within the nucleus but exist in the space surrounding the nucleus. Option D is incorrect as electrons do not move randomly throughout the entire atom but have specific probabilities of being found in different regions based on their energy levels. Therefore, option B is the most accurate description of the electron cloud model of the atom.
Question 5 of 5
Which type of muscle is characterized by voluntary control and is responsible for body movement?
Correct Answer: C
Rationale: The correct answer is skeletal muscle. Skeletal muscle is characterized by voluntary control, meaning it is under conscious control. It is responsible for body movement, such as walking, running, and lifting objects. Cardiac muscle is involuntary and found in the heart, while smooth muscle is also involuntary and found in organs like the intestines. Connective tissue is not a type of muscle but rather a type of tissue that provides support and structure in the body.
